A sonic boom is the sound associated with shock waves from a body moving at a supersonic Mach number. The weak-wave Mach cone describes a propagation geometry rather than the finite pressure signature determining the sound strength.

A sonic boom is a loud, explosive sound that occurs when an object travels through the air at a speed greater than the speed of sound, which is approximately 343 meters per second (1,125 feet per second) at sea level in standard conditions. This speed is known as Mach 1. When an aircraft or any object exceeds the speed of sound, it creates pressure waves in the air.
